Genotoxicity testing

Dear toxicologists,
I'm looking for an organization or company who could perform the Sister
Chromatid Exchange assay on a metallic biomaterial (it is in a powder
form: ~150 microns) following ISO and FDA recommandations. A price list
for this testing service would definitely be appreciated.
